数字化天气雷达图象及气象资料的数据传输

DATA TRASMISSIONS OF WEATHER RADAR DIGITAL IMAGES AND METEOROLOGICAL INFORMATIONS

摘要:

近年来,天气雷达、气象卫星云图资料都应用了数字化技术,区域气象中心实时资料库也相继建立,如何将这些资料快速、准确地传输,实现实时资源共享,充分发挥现有设备的效益,是当前气象通信急待解决的问题。我们从1988年12月起,在省级三报一话电路上实现了中/高速数据传输,有效地解决了这一问题。在我国气象通信中还属首创。

Abstract:

In recent Years, digital technique has been used in the data processing of weather radar images and meteorological satellite cloud pictures, and real-time data banks have been set up successively in regional meteorological offices. By utilizing available facilities, how to realize the rapid and accurate transmission of data and to share the real-time data resource are ugent problems in meteorological communication to be solved at present.We have achieved midium/high speed data transmission from December 1988 by the special meteorological telegraph-telephone communication lines in the provence range, firstly solving the problems in nationwide meteorological communication.
